Journey of a Red Blood Cell The Circulatory System is the main transportation for the body‚ made up of blood vessels‚ the blood and the heart. The blood is comprised of the red blood cells‚ white blood cells (lymphocytes and phagocytes which make up part of the immune system‚ engulfing invading pathogens)‚ platelets which help the blood to clot preventing infection all transported around the vessels amongst the plasma. The blood plasma contains dissolved substances including carbon dioxide‚ urea

Rate and Blood Pressure Purpose: To determine the effect of jogging on pulse rate and blood pressure. Hypothesis: If you jog then your heart rate and blood pressure will increase. Materials: Tape Measure Blood Pressure Cuff Procedure: 1. Record resting blood pressure and heart rate. 2. Measure out 100m. 3. Jog 100m (same speed every time) 4. When finished jogging 100m record heart rate and blood pressure. 5. Repeat steps 3&4‚ 3 more times 6. Calculate average heart rate and blood pressure

week on blood pressure compared with patients that do not exercise. Lewis defines hypertension as “continuous blood pressure greater than 140 over 90‚ hypertension that is not controlled.” “Hypertension or high blood pressure is an important medical and public health problem. There is a direct relationship between hypertension and cardiovascular disease‚ and a proportional increase in the risk of myocardial infarction‚ heart failure‚ stroke‚ and renal disease with higher blood pressure.” (Lewis

2013 is high blood pressure. Hypertension (HTN) or high blood pressure‚ sometimes called arterial hypertension‚ is a chronic medical condition in which the pressure in the arteries is elevated. This requires the heart to work harder than normal to circulate blood through the blood vessels. Blood pressure is summarized by two measurements‚ systolic and diastolic‚ which depend on whether the heart muscle is contracting (systole) or relaxed between beats (diastole). Normal blood pressure at rest is within

Hypertension‚ also referred to as high blood pressure‚ is a condition in which the arteries have persistently elevated blood pressure. Every time the human heart beats‚ it pumps blood to the whole body through the arteries. Blood pressure is the force of blood pushing up against the blood vessel walls. The higher the pressure the harder the heart has to pump. Hypertension can lead to damaged organs‚ as well as several illnesses‚ such as renal failure (kidney failure)‚ aneurysm‚ heart failure

under a second. 2. Explain the steps of a cardiac cycle. Ventricular filling: Happens during diastole‚ when the ventricles expand. Their pressure drops below the atria‚ the AV valse will open and the blood flows into the ventricles. The filling happens in three phases: 1. rapid ventricle filling‚ blood enters quickly. 2. Diatasis‚ slower filling of blood and P wave will occur at the end 3. Atrial systole‚ atria contracts Isovolumetric Contraction: the atria depolarizes and relaxes‚ it will
